“Even as the testimony of Christ was confirmed in you, etc.]” By "the testimony of Christ" is meant the Gospel of Christ, which bears a testimony to his deity, his incarnation, his obedience, sufferings, and death, his resurrection from the dead, ascension to heaven, session at God's right hand, and intercession for the saints; to redemption by his blood, justification by his righteousness, pardon and atonement of sin by his sacrifice, and complete salvation by his obedience and death. This, as it had been preached to the Corinthians, was confirmed and established among them, by the signs and miracles with which it was attended; by the extraordinary gifts of the Spirit, particularly of prophecy bestowed on many of them; and by the internal power and…

“That in everything ye are enriched by him, etc.]” This is still a continuation of the thanksgiving for this church, that they were “enriched”, or plentifully and abundantly provided for by Christ, with all grace, with all the riches of grace; with his own unsearchable riches, of which they were made partakers, and the riches of glory, to which they were entitled by him; and all which come to them through his poverty, which makes his grace in the donation of these riches the more illustrious: and particularly the apostle is thankful, that they were enriched by Christ “in all utterance, and in all knowledge;” that not only they had the knowledge of the truths and doctrines of the Gospel, concerning the person, offices, grace,…

“I thank my God always on your behalf, etc.]” Now follows a thanksgiving for various blessings bestowed upon this church, which is a proof of the apostle’s great affection for it, and how much its welfare lay at his heart. The object of thanksgiving is God, for as he is the author of all mercies, the glory and praise of them ought to be given to him. The apostle styles him “my God”, to distinguish him from others; and to express his faith of interest in him; and to observe to this church, that all the good things they enjoyed came from him, who was his God and their God, his Father and their Father; and for which reason he returned thanks to him for…

“Grace be unto you, and peace from God, etc.]” This is an usual salutation in all Paul’s epistles; (see Gill on “Romans 1:7”).

“Unto the church of God which is at Corinth, etc.]” This epistle is inscribed to the saints at Corinth; who are described by their being “the church of God”, a particular congregated church; a number of persons gathered out of the world, and joined together in holy fellowship, carrying on the worship of God together, and walking in all the commandments and ordinances of the Lord; a very high character this, to be called the church of God, which is the pillar and ground of truth: and it may be observed, that this is here given to a people, among whom were many irregularities, errors, disorders, and divisions; which shows, that a church of God is not to be unchurched for everything that is amiss…

“Paul called to be an apostle of Jesus Christ, etc.]” The author, or rather the writer of the following epistle; for the Holy Ghost was the author and dictator of it, and which was never doubted: he is described by his, name Paul, though his Jewish name was Saul; and very probably he being a Jew by birth, and yet born in a Roman city, might have two names, the one Jewish, the other Gentile; and by the one he went when among the Jews, and by the other when concerned with the Gentiles: and also by his office, “an apostle of Jesus Christ”; immediately called, and sent forth by him; had the Gospel from him by immediate revelation, and a commission to preach it;…
